OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 743,267, dated November 3, 1903.

Application filed April 9, 1903 To aZZ whom it may concern.-

Be it known that I, JOHN FRODSHAM, a citizen of the United States, residing at Bouldin Island, county of San Joaquin, Stateof Cali- My invention relates to an apparatus for the preparation and combustion of hydrocarbon oil.

It consists of a mechanism into which oil may be introduced in conjunction with steam or heated air and a mixing-chamber for these products, with a burner through which they are delivered to the point ofconsumption.

It also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a longitudinal central section of my invention. Fig. 2 is a top plan view of same. 7

This apparatus is designed to be used in stoves, furnaces, and like structures where it is desirable to employ heat. It consists of a chamber A, a pipe or passage 2 leading to said chamber and having a suitable controlling-valve, as at 3. This chamber serves as a preliminary heater either of steam, air, or oil. I will first describe its use for heating steam or air in conjunction with a separate oil-supply. A

In the present case I have shown the oilsupply pipe llocated beneath the supply-pipe 2 and controlled in like manner by a valve 5. This oil-supply pipe screws into or connects with the lower part of the casting in which the whole structure is formed, this casting being generally marked 6. The oil-admission pipe t connects with a passage 7, through which the oil is transmitted and wherein it is also heated on account of the casting being located in or near the furnace and subject to the heat thereof. The oil is therefore vaporized in passing through the passage 7 and in this condition is delivered into what 1 term the mixing chamber 8, with the front end of which is connected the jet-nozzle 9. This jet-nozzle projects into an'open tube, as at .10, and which may also be formed in the main Serial ll'o. 151,810. (No model.)

casting, and through this the inflammable compound is caused to pass. The air or steam which is admitted through the pipe 2 enters the chamber A and its temperature is immediately raised to apoint depending upon the amount of heat to which the device is subjected. From this chamber the heated air or superheated steam escapes through the passage 11, passing tortuously through the upper part of the chamber, thence to one side of the inlet-passage, thence diagonallydown through the casting 6 beneath the chamber A, and eventually forms conjunction with the oiladmission pipe 7 at the entrance to the chamber 8. The two passages 7 and 11 meeting at an angle, the oil or the vapor produced from it and the steam or air will thus be mixed in the chamber 8 and thence delivered through the burner-tip, as previously described. If the mixture thus formed provides sufiicient oxygen for proper combus air into the passage 10. a

In some cases it may be found desirable to admit the oil directly into the chamber A, in which case the supply of oil would pass through the passage 2, be delivered into the chamber A, where suflicient heat is applied to vaporize the oil. The oil then passes through the passage 11, as previously described, and is delivered into the chamber 8 and from thence discharged through the jet of the burner. In such case the passage 10 is shown extending rearwardly and having an opening, as at 12, through which air may be admitted into the passage, and by the draft or suction caused by the jet of oil sufficient air would be admitted to provide for the combustion. This admission-passage 12 is controlled by a slidable or other gate 13, by which it maybe closed at any time when not in use. Any sur plus oil or drip is retained in the tube or chamber 10 by flanges, as 10, the front one also contracting the discharge.

The casting 6, containing the various chambers and passages, is designed to be located within the stove or furnace, so as to be subjected to as much heat as may be found necessary for vaporizing the oil and for heating or superheating the air or steam which may be introduced. When used in conjunction tion, there will be no need to admit any other with small fire-pots, the device may be so placed as to be subjected to radiant heat from the fire-pot, or it may be sufficiently heated from the burner itself.

Having thus described my invention, what I claim, and desire to secure by LettersPatent, is

drocarbon liquids consisting of a casting having a chamber in the upper part, and a passage in the lower part, a mixing-chamber with a jet-tube discharging from its front into the lower passage, a pipe through which oil is supplied to the rear of said mixing-chamber, a pipe through which air or steam is admitted into the upper chamber, and a tortuous passage extending through the casting from said chamber forming a junction with the oil-supply pipe at the rear of the mixing-chamber. h In Witness whereof I have hereunto set my and.
